How do you keep commands from echoi

[mikevh]

How do you keep commands from echoing as you type them at the command prompt? I was sure it was "echo off" (and "help echo" seems to support this), but all that seems to do is make the command prompt disappear --
it apparently has no other effect. Your commands still appear as you type them, and output still appears as normally.

Reason I ask is someone else asked me and I confidently told them "echo off", then was shocked to find this didn't work. (Last time I tried it was probably DOS 3-point-something.)

This is on Win XP [Version 5.1.2600].
Thanks.

There is no command line directive to suppress the echoing of keyboard input. In a .bat or .cmd line you can use the echo off command; the in-line suppression command symbol "@"; or carefully use the CTTY NUL redirection commamnd. But not at a command line.
